Apple Mac Studio (M5 Ultra) review: top benchmark scores, but it costs around twice as much as the M5 Max model without delivering nearly double the performance

Context & Ripple Effects
Apple positioned the M5 Max and M5 Ultra Mac Studio as a performance and AI-capacity refresh, with configurations reaching 512GB of unified memory in its August M5 Studio launch. The choice arrives after higher Mac mini and Studio entry prices, making the step-up cost more consequential for workstation buyers.
The prior M3 Ultra model was already praised for performance and quiet operation, but its memory and SSD could not be upgraded after purchase. That makes the M5 Ultra’s price-to-performance gap a purchasing decision that buyers must get right at configuration time.
First-order effects
Apple’s Mac Studio buyers have a clearer value split: the M5 Max offers the more defensible option when M5 Ultra benchmark leadership does not translate into nearly proportional performance.
The M5 Ultra retains its role as Apple’s highest-performing compact workstation, but its roughly twofold price premium narrows its immediate audience to workloads that can use its additional capacity or speed.
Second-order effects
For Apple, the M5 Max becomes the configuration against which the Ultra tier’s premium must be justified in application-specific workloads rather than benchmark rankings alone.
Buyers planning local AI work face a sharper trade-off between paying for the Ultra configuration’s maximum memory headroom and selecting the lower-cost M5 Max model for stronger price-performance.
Third-order effects
The fixed-memory Mac Studio lineup pushes workstation procurement toward upfront workload sizing: buyers cannot cheaply correct an underspecified memory or storage choice later.
If the performance-to-price gap persists across flagship tiers, compact workstations will be judged less by peak benchmark wins than by whether specialized AI and creative workloads materially benefit from the premium configuration.
The trend: AI-capable workstations are shifting from a race for top benchmark scores toward configuration decisions based on usable memory capacity and workload-specific value.
Great review of the M5 Ultra by Federico and let's keep in mind these numbers are just the starting point, everything will just get better in the upcoming weeks! Can't wait to try one and buy the 512GB version!
I have been using the Mac Studio with M5 Ultra for the past week, and it's the most powerful computer I've used. Been a bit busy over the past week so my report will be slightly delayed, but just know... Qwen 3.8 Flash Next is the best model for the 256GB version, it rips
I ran all the M5 Ultra tests I could think of: - Two models (Flash-Next and GLM-5.3-Flash) - 4k, 8k, 16k, 64k, 128k, and 256k prompts - M5 Ultra vs M3 Ultra vs RTX 5090 - 4/5/6/8-bit Flash-Next quants I created all the possible charts and visualizations I could think of. Hope the…
The M5 Ultra Mac Studio is INSANE! Apple sent me the maxed out version, with a 36-core CPU, 80-core GPU and 256GB of RAM. I used it to run Deepseek v4 Flash (156GB model) fully on device to build a mini-game, which it did in just a few minutes! #MacStudio #M5Ultra @apple
M5 Ultra's prefill speeds are up around 150% vs M3 Ultra when running Qwen3.8 Next Flash 🤯 Strong numbers! I wonder what the prefill speeds would look like with a model that has more active parameters. Qwen3.8 Flash Next has only 6B active.
We got an early unboxing of the 2026 Mac Studio, and Apple packed serious internal upgrades into this compact workstation. 🤖🚨 Powered by either the M5 Max or the new M5 Ultra chip with up to a 36-core CPU and 80-core GPU, it delivers up to 4.3x faster local AI performance and sig…
Been using the M5 Ultra Mac Studio for the past week and predictably it is the most powerful computer I've ever used. At this point, the improvements are not even targeted at me (a video creator) anymore. They're targeted at being the best machines for local AI work. There's noth…
The other thing I noticed was this was the first time where I could run a ton of subagents, with cloud models, and each had access to enough CPU resources that it wasn't really limited. It also compiled rust like 2x faster than M3 Ultra
I ran all the M5 Ultra tests I could think of: — Two models (Flash-Next and GLM-5.3-Flash) — 4k, 8k, 16k, 64k, 128k, and 256k prompts — M5 Ultra vs M3 Ultra vs 5090 — 4/5/6/8-bit quants — I created all the possible charts and visualizations I could think of. …
